ci: k8s: Add a function to deploy k3s

Browse Source 
One can use different kubernetes flavours for getting a kubernetes
cluster up and running.

As part of our CI, though, I really would like to avoid contributors
spending time maintaining and updating kubernetes dependencies, as done
with the tests repo, and which has been proven to be really good on
getting things rotten.

With this in mind, I'm taking the bullet and using "k3s" as the way to
deploy kubernetes for the devmapper related tests, and that's the reason
I'm adding a function to do so, and this will be used later on as part
of this series.

It's important to note that the k3s setup doesn't take into
consideration a BM machine, and this is not suitable for that.  We're
really only targetting GHA runners which will be thrown away after the
run is over.
